You may have fixed this already in later builds, but in 3.7.209.18969 your link to the google fonts in _Root.Head.cshtml is using http. You need to use https or some browsers throw a "HTTPS security is comprimised" message when accessing secure pages.

It would be nice to have a separate setting to hide the "Estimate Shipping" panel in the OPC page. For implementations where we still display the default Nop cart page, this is redundant and takes up a lot of valuable real estate.

This isn't really a bug per se, but the Ajax Cart items take up a LOT of horizontal space in the Brooklyn theme. You can only see a few items in the dropdown which kind of negates the point of the Ajax Cart in the first place.

I'd suggest you make that smaller by default, but if not, is there an easy way to reduce the vertical space for each item (or make the dropdown scrollable)?

Same with the "Update Shopping Cart" button on the shopping cart page (not respecting the selected color). There may be more ... You may want to do a quick QC test on this color presets for all of the pages in this theme.
